just informed myself about diamond dependency problems, i.e. the problem when a package A depends on package B and C which both depend on another package D, however with different versions. I.e. package B uses D v1.2 and C uses D v1.3. The crux in such a setup is that you cannot easily pass results…

At any given moment, you only have one “virtual environment” active. The requirements of A will determine the versions of B and C, and their requirements will in turn determine the version of D. In your example, C requires D v1.3 and so this is the version of D to be installed, not the older version…

How does the julia 1.0 Pkg handle diamond dependencies?
